Energy-efficient time-bounded wireless sensing networks

Existing works that preserve sensing coverage and connectivity in wireless sensor networks at all times lead to inefficient use of battery power. Motivated by the time-discrete nature of application data sampling, we redefine the problem to have guaranteed coverage, connectivity and delay within some known bounded time. We further explore a class of wakeup schemes based on the cyclic symmetric block design (CSBD) that offer bounded-time characteristics to better manage energy usage. We made simulation studies of our proposed scheme, and investigated the impact of such wakeup schemes on an application-layer data fusion algorithm.
